Area of Science:

Neuroscience
Artificial Intelligence
Signal Processing

Background:

Electroencephalography (EEG) signals are crucial for understanding brain activity.
Detecting mental performance from EEG data requires advanced feature extraction and classification methods.
Existing methods may lack interpretability, limiting their application in neuroscience.

Purpose of the Study:

To develop a novel feature extraction method, Different Pattern (DiffPat), for enhanced EEG mental performance analysis.
To integrate DiffPat within an Explainable Feature Engineering (XFE) framework for both classification and explanation.
To improve the accuracy and interpretability of mental performance detection from EEG signals.

Main Methods:

Utilized an EEG mental performance dataset.
Developed the DiffPat algorithm for efficient EEG channel difference-based feature extraction.
Employed iterative Neighborhood Component Analysis (INCA) for feature selection.
Applied K-Nearest Neighbor (KNN) classifier for performance classification.
Generated AI-based explainable results using XAI and Directed Lobish (DLob) for cortical connectome diagrams and interpretive sentences.

Main Results:

Achieved 84.48% accuracy using leave-one-subject-out (LOSO) cross-validation for subject-independent performance estimation.
Attained 99.87% accuracy with subject-aware 10-fold cross-validation.
Demonstrated the model's capability for both accurate classification and result explanation.

Conclusions:

The DiffPat-based XFE model offers significant advancements in feature engineering and neuroscience.
The model's dual capability of classification and explanation holds strong potential for mental performance analysis.
This approach is applicable to a wide range of EEG-based applications beyond mental performance detection.
